WINDOWFRA|VI E.

SPECIFICATION forming part of Letters Patent No. 475,438, dated May 24, 1892.

l Application iiled May 25, 1891. Serial No. 394,030. (No model.)

To a/ZZ whom it may concern:

Be it known that I, EDWARD C. CONWAY, of Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements inVindoW-Frames and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specication, and to the figures of reference marked thereon.

My present invention has for its objects to provide a window and window-frame that will not only be cheap and simple' in construction, but that will be adjustable, so that all shrinkage and wear may be taken up and the sashes caused to always Iit tightly or suciently so to prevent either rattling or the passage of air and dust; and to these and other ends the invention consists in certain novelties of construction and combinations of parts, all as will be hereinafter described, and the novel features pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a view, partly in section, of a window-frame; Fig. 2, a vertical sectional view of the same on the line a; fc of Fig. 1; Fig. 3, a cross-sectional view on the line y y of Fig. 1; Fig. 4. a vertical sectional view through the edges of the sashes and the parting strip or stop. Fig. 5 is a sectional view taken on the linee' z of Fig. 3, and Fig. 6 a similar view on the line a b of Fig. 2.

Similar reference-numerals denote similar parts.

The main casing or window-frame is constructed, as usual,with the sides 1 1, the upper timber 2, and the sill 3, and is adapted to be secured to the studding, as usual. To the inner side ot this frame is secured the inner stop or strip 4., having slots therein, through which pass securing-screws v5, entering the casing, thereby permitting the adjustment when desirable or necessary.

The central parting stop or strip 6, between which and the inner and outer stops the sashes slide, is preferably secured in a slot in the side 1 of the casing, and is constructed as in Figs. 2 and 4., its outer side being beveled or cut away from near the top to the bottom and its inner side cut away from the bottom to the top, and the inner sides of the upper and lower sashes 7 and S, respectively, are correspondingly beveled, while their outer sides are straight, so that if the outer guides for said sashes are parallel the windows when closed are held tightly in position and a close joint made, preventing movement in or out; but when they are open free movement will be permitted them. The face of the stop 6 is also beveled or cut away from the center toward the ends, and with this Jface co-operate the edges of the meeting-rails 9 of the sashes, which overlap it, as shown, thereby insuring when the windows are closed a tight iit, preventing their lateral movement, but permitting them to move without binding when opened.

The outer frame 10 of the window embodies the upper horizontal portion and the two side pieces,(only one of which, however, is shown,) and this frame is provided on its inner side with a groove 11, in which the edges of the stationary frame or casing 1 2 are received, making a reasonably-tight joint and preventing the entrance of, wind or dust. As the inner edge of this frame forms the outer guide or stop for the upper sash, it is adjustable, and various means may be devised for the purpose, one of which is shown herein, consisting of screws or bolts 12, passing through the frame from the outside and engaging a nut or plate 13, provided with a threaded aperture secured to the face of the inner casing 1. For preventing the longitudinal movement of the screws 12 in the frame 10 and insuring the movement of the latter I provide plates 14., having projecting legs 16 thereon secured to the inner side of the frame, said legs engaging the annular grooves 15 in the screws.

The sashes when closed are by reason of the beveled surfaces held tightly, preventing rattling or the entrance of air or dust; but the upper sash may be moved down and lower one up freely, they being suspended, as usual, by weights or springs.

The inner stop or the outer frame constituting a stop may be readily adjusted by means of the screws 5 and 13, so as to cause the sashes to fit more tightly or loosely should they become loose or stick.

IOO

The advantages derived from such a structure as mine will be at once apparent to those skilled in the art, among which may be mentioned simplicity and the ease of construction, the adj ustability of the parts, thereby compensating for wear and shrinkage and keeping the Window-sashes tight when closed, but permitting their ready operation, when desired. A

I claim as my invention- 1. The combination,with the stationary Window-frame having the sash-stop thereon beveled on one side, of the movablefrarne adjustably secured to the window-frame, one of the edges constituting a sash-stop, and a sash movable in the window-frame, having a beveled face co-operating with the one on the stationary stop, substantially as described.

2. The combination,with the stationary window-frame and the parting sash-stop thereon beveled on opposite sides, of the frame adjustably secured to the stationary frame, one of its edges constituting one of the sash-stops, and the sashes provided with the beveled inner sides co-operating with the sides of the part ing sash-stop, substantially as described.

3. The combination,with the stationary window-frame and the parting sash-stop thereon beveled on one side, of l.the movable frame adj ustably'connected with said stationary frame having the groove for receiving the edge of the latter, one side of said movable frame constituting a sash stop or guide, and a sash operating therein, substantially as described.

4. In a window-frame, a partingstrip orstop having the face inclined from the center toward each en d and having the sides inclined in opposite directions, in combination with the upper and lower sashes correspondingly inclined on the sides next the parting-strip and having the shoulders on the meeting-rails engaging the face of the parting-strip, substantially as described.
